20 ppi has a point to depth of about .030” . Finer checkering will be shallower. I have read that the minimum thickness under checkering should be .030” also. Considering any thinning of the front strap to true it, I’d shoot for .070- .080” initially. The forum in the past has had reports of sections breaking out when straps got too thin. Frames have had to be machined out and an EGW frame patch welded in to save the frame. Not sure a Tisas would be worth the save cost. Measuring the strap thickness provides a challenge. I use a brake rotor mic repurposed from my auto tech days. Like this:

Well Joe, I may have that tool covered, I am in the auto repair biz myself. On the other side, I've been a parts dept. mgr for almost 30 years. With a part time fill in as svc mgr (yuck 😆) and asst body shop mgr.
Ahhh! A reason for the metalwork fearlessness! I was 40+ years in GM shops. Last 4 as shop foreman. Never aspired to higher management posts, I get the yuck part…
